Therapeutic Ultrasound 2D: Tissue Cross-Section Heating Model

Therapeutic ultrasound is one of the oldest deep-heating modalities in physical therapy: a handheld applicator radiates high-frequency acoustic energy into skin, fat and muscle, and the tissue's own absorption converts that energy into heat at depth. This 2D cross-section renders a fine-grained slice of layered tissue and drives every cell's temperature from the same physics a clinician relies on — frequency-dependent attenuation, a Gaussian beam profile, and perfusion-mediated cooling — so switching from 1 MHz to 3 MHz visibly moves the hot zone from deep muscle to the skin surface. A depth-temperature profile and a peak-temperature time trace sit alongside the main heatmap, and the cross-section itself can be panned and zoomed. Adjust intensity, duty cycle, applicator position and tissue perfusion and watch peak temperature, penetration depth and elapsed treatment time update live, exactly as it would on a real ultrasound unit.
